  1. The key components in laser gyro is he - ne ring laser, and the reciprocal action theory between light and medium is the base in studying the ring laser, use the lamb half classical theory, and on the base of density matrix theory, the optical brounch equation was established, which described the movement of amplifying medium atom in the ring syntonic cavity, and according to the medium polarize theory the self consistent equations was deduced, which describe the light intensity and phasic of the counter - propagating wave. on the basis of this equations, adopted the simulation software matlab and virtual instrument programming language labwindows / cvi, we can do some simulated experiments in study the phenomenas such as amplify and dispersive characteristic of medium, mode pushing effection, burned hole effection and pattern competition, lock - in of frequency and the characteristic of light intensity and phasic of the counter - propagating wave in laser gyro

    激光陀螺的核心部件為he - ne環形激光器，而掌握光與介質的相互作用理論是研究激光器的關鍵，採用拉姆半經典理論為主，在密度矩陣理論的基礎上，推導環形諧振腔中描述he - ne氣體增益介質原子運動的光學布洛赫方程，運用介質極化理論得出描述激光陀螺反向行波的光強、位相所滿足的自洽場方程組，在此基礎上，運用matlab模擬軟體和虛擬儀器編程語言labwindows / cvi ，對激光陀螺中的介質增益色散特性、頻率牽引效應、燒孔效應及模競爭、閉鎖效應及環激光的光強和相位特性進行模擬試驗研究，並且運用全量子理論，對激光工作原理進行分析，得出二能級系統單模輻射場的光子數密度分佈，得出激光場的光子統計分佈，模擬激光場的動態建立過程。
  2. So for some special patients, zona drilling or local zona thinning with increased z ptv may help embryo hatching. at the same time, different types of assisted hatching have been developed, such as mechanical tearing, chemical digesting and laser burning

    因此，對一些特殊病人進行透明帶打孔或局部減薄提高zptv或許有助於胚胎孵出及種植；與此同時，多種輔助孵出方法也在被人們嘗試使用，如機械切割法、酸化學溶解法和新近使用的激光燒灼法。
  3. ( 3 ) there are many flaws in direct laser metal sintering, such as the high remnants stress, micro - hole and micro - crack in sintering parts. in order to solving those problems, the programming of scanning paths is put forward, and several parts are prepared with different scanning paths respectively. the following conclusion is educed : the parts produced with short - side scanning path and same scanning direction have the minimum structure, the rigidity of parts prepared by short - side and same direction scanning path is highest, and the density of parts produced with the vertical scanning path is maximal

    （ 3 ）針對採用大功率激光直接燒結鎳基高溫合金成形金屬零件存在的問題，如較大的殘余應力，製件中存在著微裂紋、微孔洞等缺陷，初步提出掃描路徑的規劃，並採用幾種不同的掃描方式進行燒結試驗，發現採用短邊掃描路徑和同向掃描能夠獲得更加細小和分佈均勻的組織結構，採用短邊同向路徑制備的試樣其顯微硬度最高，而採用變向掃描（垂直）路徑制備的試樣緻密性最好。
